I bought 3 of these to use HK Link. IMPRESSEDI got 3 of these to use the HK Link to try and make a whole home audio setup without the setup of Wifi devices in my remote cabin. The 3 units are in separate rooms and all connect seamlessly and easily together to make a great whole home audio solution. Great job Harman!!

Amazing sound... Bad app for Stereo modeI've become a Bluetooth speaker junkie and these are wonderful in all areas, execpt two the app to connect stereo mode is a test of patience..plan a extra 15 minutes out of your day ,never seems consistent no matter what divice I'm pairing with and more than half the time the app just keeps closing.. I also wish they had Auto shutoff after a certain amount of time like my Onyx minis do . But other than that the best for home use, get 2,put in stereo mode (eventually), keep them plugged in for extra ummpphh and enjoy ....

is this speaker a stereo or mono speaker?

Asked by: davdadoc

Thanks for your query.
The HK Onyx Studio 4 is a mono speaker. It can, however, be connected with another Onyx 4 to form a stereo pair via the HK Connect app.
If you have further questions, do not hesitate to contact us by phone, email or chat to get individual help.

I have 1 Onyx4 and looking to purchase another. I have 2 questions before buying another. If I have one connected to the TV can I use HK Connect+ to connect the 2 speakers together into a stereo config? Or can I connect both with an aux splitter? Thank

Asked by: JakeNew

Thank you for your question.
It's not possible to use the Connect+ feature on our HK Onyx Studio 4 models, when the source is a (analog) TV signal. Connect+ only works when the source is a mobile device which can run the JBL Connect App ( such as iOS and Android mobile devices ). If you wish to enhance the sound of your TV, we would recommend using one of our Soundbars for this.

I bought Onyx Studio 4 and noticed that if any connected device is silenced for about 5 seconds, the speaker just turned off by itself and then delayed turn on (about 2 sec) if the connected devices sends audio signal. How to disable this behaviour?

I have just purchased an Onyx 4 and I am so impressed I want to order a second.
If I use the app to pair them in stereo, will they stay in stereo, or will I need to use the app and select the stereo option each time?

Asked by: Nick G

Thank you for your question.
I am glad you are enjoying your Onxy Studio 4 speaker. However, yes the app will not remember that you put the speakers into stereo mode, so will need to do this each time you turn the speakers back on.
Should you wish to receive further support, you may contact the Harman Customer Support team by telephone, email or chat in order to receive direct assistance.

Does the Onyx Studio 4 speaker use the aptx codec? (my Onyx Studio 2 does not) If not, why not? I especially like the low latency of aptx for movies.

Asked by: Gtbuzz

The Onyx studio 4 doesn't support Aptx as the Onxy studio 4 is mainly used for music which doesn't require Aptx .
